This is the earliest build of Windows 95 leaked, there are no references to Windows 95 yet, just the codename ''Chicago''.
It installs via a batch file that opens the Mini Windows from the \MINI folder, it is a basic Windows 3.1 version consisting of the core files.
After clicking through the screens, it copies the Windows installation to the \CHICAGO folder and then reboots.

After the reboot you see a background with UNDER CONSTRUCTION and a warning that the interface can still change.
It includes the a basic explorer (called CABINET) with a Windows 3.1 look including a taskbar.

We recommend doing this on Microsoft Virtual PC 2004 with an older PC.
Install MS-DOS 5, then change DOS=HIGH to DOS=LOW in CONFIG.SYS.
Copy the installation files to a folder on the HDD including the subfolders(we use \WIN95) and then run DOSSETUP from that folder.
